Love Polk Audio but....

Ken from Dallas, TX on 8/15/2016

2013 Ford F-150 XLT

I replaced the fronts in my 2013 F50 with some Pioneers that were a little cheaper than the Polk. Both are a good match for the specs ( low wattage factory radio so I went for low RMS with good sensitivity). I got a gift certificate and thought I would use it to replace the rears. Being a long time PA fan thought I might upgrade a little more when doing the rear doors and was excited to order the DB571's. Gotta say these are not in the same class as the Pioneers. A huge response difference. Expected quite a bit more out of the Polks and would trade them in an instant for another pair of the same Pioneers. Better than the factory cheapos but really- not by that much. It could be just this pair I got but yeah, a bummer.

Pros:Price and ease of install

Cons:Muffled sound, less of everything (not just bass) than others in the price range. A let down for a Polk Audio product.

Polk Audio db571 - 1999 F-150

The sales rep made the order process easy. Shipment was fast. Installation was quick. The order came with the wiring converter harness.

Pros:Easy install

Cons:The speaker was not a perfect factory fit. Only two of the four screw holes lined up. The converter harness made the installation easy but the clip would not latch closed. I had to secure the connector with electrical tape to insure that it would not come a part over time.

Third pair of DB series Speakers

Great overall speakers. I put these in my boat recently and was jealous of the sound they put out vs my stock F150 speakers. Put the db571s in the truck along with a new HU, great sound quality and improvement.

Pros:Install was 4 screws out, 4 screws in, perfect fit

Cons:none

Great little speaker

Very happy with the speakers, especially when considering they were replacing 27 year old factory speakers that hadn't worked in 20+ years... They are a very nice high efficiency speaker with a great price.

Improvement to a point

As stated elsewhere, an immediate improvement over poor factory speakers. Initially tested on head unit with approx. 12 watts RMS per channel. Boosted with Alpine pushing 45 watts RMS, and improved again...nice, clear sound for the price. Only reason for pulling a star is that lower range performance is relatively weak and somewhat muddy, even for a lower end speaker. Have subs, so don't particularly rely upon to reproduce bass to any substantial level. For a system without subs, you may be disappointed.

Pros:Good price for sound quality.

Cons:Poor performance at lower notes.

Nice up grade

Replaced factory speakers.with the Polk db571.a cleaner more precise sound..from the Polk ... Factory speakers weren't awful.. the polks sound better responsive and bass.. and have more potential. With maybe a day and a half or new head unit later. Install was easy..

Polk 5x7 in Van

My door panel had an oval for only a 5x7 speaker and would not accept the 6x8 / 5/7 speakers. The DB571 speakers were a tight fit with the recommended speaker baffles. But with crushing the foam of the speaker baffle around the speaker frame, the speakers did "fit". Too bad Crutchfield did not have a replacement mounting bracket to replace the factory 5x7 bracket. Then Crutchfield would have alternatives to the new standard of rating 6x8 speakers as fitting in a 5x7 hole.

Pros:Speakers sound good.

Cons:Nothing that relates to the speakers.

Polk Audio Speaker Replacement

My wife bought a pair of these speakers as a Christmas gift. I complained that my front speakers sounded a bit blown to me. Because of lots of other projects going on I didn't get to install right away, that's when I noticed my rear speakers started to sound them same way, so I ordered another pair. I made time this time to install all four speakers at once and glad I did. Installation of the speakers themselves was fast and super easy. Taking off the door panels without damaging them took the most time for me. These speakers made a big difference to my audio system. I recently installed a Pioneer FH-X721 receiver, this paired with my new Polk speakers have me driving happily down the road listening to some great tunes from my music library.

Great sound

These speakers are leaps and bounds above the factory speakers I replaced. WOW!!!! With the new stereo cranked all the way up, there was absolutely no distortion and frankly extremely loud. My ears hurt, but I had to test their effectiveness.

Pros:Excellent sound

Cons:Mounting holes were ever so slightly off from my OEM speakers, but were within specs and were definitely mountable. Love the sound.

Simply put... Quality

From the second I took this set of speakers out of the box. I was overwhelmed by the precise attention to detail and quality that was put into this speakers manufacturing process. I almost thought I made a mistake buying the other set of speakers which were pioneer, as opposed to going with a second pair of these polk. However, together the sound was exactly what I was aspiring for. These polk gave an eloquent reproduction of sound at nearly every level of volume. If your not worried about the heavy bass people for some reason expect out of door speakers then there are a perfect choice. The bass was less than I thought would be there, with that said the clarity blew me away and made up more than enough for it. The pioneers gave me the bass I was looking for and complimented this pair perfect.

Pros:Exceptional clarity and sound reproduction at every volume level. Marine use certified and high level quality engineered.

Cons:Somewhat lack of bass response but if your end goal is to put subs in then that point becomes moot.

Great for the price

The price is right, and these speakers solved my problem. My factory Ford Escape speakers lacked clarity, and I could not hear certain background vocals. The install of these was very simple, and as promised by Crutchfield Sales Support I can very much hear the difference. I didn't need an amp either so I'm thrilled.

Pros:Works great, good price, easy install, amp not required

Cons:The install steps didn't specify that I would need to tape the cable to the inside of the door during the install or else the window rubs. I wish I had known this to save me time.

Polk Speakers For 2008 Mariner

I love these speakers, great sound. Much beteer than the factory installed speakers.

Pros:Great quality sound. Easy installation

Cons:They were not a perfect fit, one of the screw holes was a little off center.

Wrong Aproach

Igo from Nevada on 5/25/2015

2008 Mazda 3

OK, here's a review of these speakers installed in a Mazda 3 in 2008. Overdue? Maybe, but there is a reason. I have a 100x2 RMS amp for up front and a 50x2 for the back door speakers. In 2008 I decided to use these Polk speakers in the back door because they were rated at 93db for efficiency and for a 5x7 they claimed to reach down to 52hz frequency. My reasoning was that I could get as much wallop from the 50x2 amp as the 100x2 up front with better component speakers. Wrong way of thinking. Instead I ended up moving the sound stage and imaging almost completely foward and barely heard these speakers for anything more than ambient sound. A good thing. Well my 19 year old subwoofer finally died and I found myself re-examining my aging system while trying to trouble-shoot the old sub. I moved the fade to a neutral state between front and back and discovered these back speakers greatly degraded the overall system sound. My determination? Something has to give when you try to squeeze 52Hz out of a 5x7 speaker and 93spl just doesn't come out of a speaker this size without a great deal of loss of voice coil control. So, yep, after 8 years I am trying a set of 88db efficiency 6x8 speakers only rated to 80Hz. And this time I am only relegating the new speakers to ambient duty as their principal function. Summary: The old Polk 571db simple ran muddy in modest lower throws with apx. 70hz thru 140hz notes pretty much stepping on each other rather than being defined, separate notes.

Pros:

Cons:I've been a Polk fan for many years, these were just a miss.

Polk db 571

Great upgrade sound much better than factory speakers, can hear so much more and more clarity. Front speaker in 06f150 had to cut side tabs to fit proper but very easy installation .. Would reccomend highly . Another satisfied customer

Award winning

I love these speakers! For the money they are really great! Crystal clean an good bass an mid bass! I use to do car audio completion and used Memphis Audio an these polks are better than the speakers I was paying way more for! Great sound quality

Nice upgrade

I bought this for my 2004 F150 super cab. I am pleased overall, but I expected a bit better low end. The highs are nice and much improved over the single come stock speakers. I think my problem is the stock head unit now. In retrospect, I might have waited and bought some thing higher end as part of a complete system, but for the price for four of them, I'm happy. The installation was amazingly fast and easy!

Excellent factory replacement choice

Finally decided (after owning the truck for over 2 years) to replace the poor quality stock (Sony system with GPS) door speakers. My only regret is that I waited this long to do it, very pleased with the quality of these Polk speaker and with the excellent instruction provided by Crutchfield it was a snap...only took about 10 minutes per door.
Great high end and good low end, can turn it up to my favorite rock and country tunes, or listen to talk/news radio with no vibration or cracking noise.
I debated over a couple of different speakers choices and the agent at Crutchfield did a great job of explaining the pros and cons of the various choices i had narrowed it down to.

Pros:Excellent high end reproduction, crisp clean sound

Cons:Simply that I needed to re-adjust the bass and treble after the speaker replacement, it still left the bass sounding a little disconnected/flat, but was able to modify the stock Sony sub with some fiberfill to help give it more depth. Sounds outstanding now!

Nice Mids, So-so Lows

I ordered these speakers expecting a great sound. Polk did not disappoint. Though they say they fit my 98 ford ranger, and they did, the did so a little awkwardly. The highs sound crisp and clear, the mids come through great, but the lows.....ehhhh. I was hoping for some deep tones. They do produce some rich lows, however, if you are going for bass, you need a woofer. These speakers don't thump, they sound a little distorted when I try to push them, but when I tone it down a little the sound is amazing! A great choice if you want to replace a blown speaker or some factory insets. I really couldn't be happier with this product. The install was a breeze! Total install time took me about 10 minutes. Worth the money.

Pros:Crisp Sound, good highs and mid range

Cons:Bass response isn't all that great, awkward fit

Great Speakers!

I installed 4 speakers in my 2005 Ford F-150 FX4 Supercrew two weeks ago and were an instant step up from the stock speakers. The front two fit perfectly, and the rear two took a little more effort making a few adjustments to the frame to make them fit. Just installed a pioneer head unit with these speakers, and I have no regrets. The midranges are excellent; the low bass lets its presence be known and shakes the mirrors a bit. Overall great quality for a great price!

2004 F350

Fit perfect using the supplied wiring connectors. Sound much better than the 10 year old stock speakers. I also liked the fact these are marine grade. Work trucks do tend to get wet on the inside occasionally.

Db571

Polk Audio was on sale at the time I bought these and in addition to the numerous good reviews, I went ahead and purchased two sets (required for my 2003 Expedition). They definitely sound more clear than the stock speakers. The speakers unfortunately didn't fit perfectly, but by using some gardening shear scissors I was able to cut off the two loops at the tips of the speakers. I also had to drill two holes as only two of the side mounts matched up with the stock holes.

Pros:SQ way better than stock.

Cons:Doesn't fit perfectly.

Polk Audio db571

These speakers are a very nice upgrade over stock paper speakers. There is SIGNIFIGANTLY more bass and the sound is much clearer overall, even with the stock head unit. These were put in a 1999 F250 work truck that has a very lame am/fm receiver, very basic. The sound quality has dramatically improved.

Midrange upgrade

ajw15 from Byram, MS on 7/31/2014

These speakers were a fast improvement from the stock speakers in my Mazda Tribute. Very easy to install and really helped up the high and mid range sound so my two subs would not over power the rest of the musical quality.

Pros:easy to install, great sound, great look

Cons:none

Great upgrade

Installed these speakers in a 2007 Ford F150. The instructions and the wiring harness made everything easy. Only took half an hour. The sound is a vast improvment on the stock speakers.. Bass is very clear and loud . The gold color of the speakers looks great through the grille on the doors. I would reccomend these to anyone looking for better sound even with my stock receiver( which I plan to upgrade next.

Pros:great speaker, looks good, marine certified

Polk Audio db571 speakers

Have had other Polk Audio home products and thought these would meet higher expectations in my truck. While they are a good sounding speaker, they are not of the same quality as their home products. Really not much difference in sound between the factory ones I replaced.

Pros:Polk name.

Cons:Overall sound quality is not there.

Polk 5x7's

These are the first oval speakers I have purchased in over 10 years. Happy to say I am very impressed with the sound. My highs currently seem a bit full of crackle but that is more than likely due to my not finetuning my system yet. I love the look and construction of these speakers.

Pros:-Solid construction
-Great value for price

Cons:-Can't rotate/direct tweeter

Inner ear

Yes this is the ticket for real quilty some when you really want to hear everything that's going on in listening to your music. I've also noticed the fact that these speakers are built pretty durable as well as performance in their output of sound Quility. You can't go wrong using these speakers to get the job done with sound Quility.

Pros:The pros here is simply sound Quility and the durability of the overall construction of these speakers. Now did I mention the Quility!!!

Cons:The pros here is that I didn't take the opportunity of researching these speakers sooner. That to me is the con here.

Polk Delivers Again: Replacing FLM 5x7 Econoline Speakers

The Polk db571 is an amazing upgrade to factory Ford 5x7. In my case, the foam surrounds had all but disappeared from age. Installation was virtualy painless.

Pros:The marine certification and rubber surrounds are an ideal choice for a work truck. But the improvement in fidelity, clarity and efficiency is the real payoff.

Cons:The plastic spacers provided to keep door trim off the surrounds are simply taped to the speaker frame, and have the potential to vibrate. I used a vinyl & rubber adhesive to glue the spacers firmly to each frame before installing.

Great Sound - 2012 Ford F150 Super Cab

The Crutchfield adviser Cooper suggested these speakers, Polk Audio db571, to match up with my Pioneer AVIC 900BT. I took a long time to decide, having thought the Infinity Reference speakers would be better. I trusted Cooper and went with the Polk Audio speakers. I did however completely cover my doors with dynamat sound deadening material. This was suggested in another forum and was well worth the investment. The sound is crisp, full range and has a surprising level of punch. The equalizer of the Pioneer received allowed me to fine tune the speakers for my personal preferences. I initially installed one speakers and tested to see if it sounded better than the factory speaker and was disappointed. I did the same after installing the second speaker and was not impressed. After installing the third speaker I was thinking maybe I won't send them back. When finished with the complete install of all four speakers I was amazed at how good they sounded. After adjusting the equalizer I was completely sold on the fact that these were the best speakers in that size for the money I spent. The speakers were on sale buy one pair, get the second half price.

Pros:Crisp highs, full range sound and surprising level of punch to the base. The speakers were a breeze to install and the adapters worked perfectly. I would highly recommend the Dynamat material

Cons:May need hearing aids eventually! The speaker sound so good I'm playing them more often and louder than usual because they sound so good.

Polk speaker install 2006 Ford F-150

These speaker sound better than factory, but I would have liked a fuller sound. Also I think Crutchfield should have suggested the deadening pads for the doors, that would have made a difference. I learned about them afterward.

Pros:Ease of installation, decent sound, the wiring adaptation was perfect.

Clear full range sound

I love the way they sound. They are not bass dominate. The highs are awesome but if your into bass heavy sound then you might not like these. These speakers give you a clear full range sound with descent bass and crystal clear highs.

Pros:Highs
Clear sound

Cons:Bass output is average

Polk Audio db571

I replaced my factory speakers in my 2003 F-150 supercrew (2 pair 5x7). I also have replaced the factory deck with a Pioneer DEH-X6600BT. I am running a Zapco 4x75 rms amp. These speakers sound exceptionally clean and crisp. Considering they are 5x7 coaxial speaker they are well worth the money. For what I am using them for they work great. Not sure how they handle lows since I am running a crossover. Didn't buy them for lows though. I would recommend them for a factory replacement any day.

Polk Audio db571

the polk speakers I purchased work very well. I had upgraded the factory stereo with a pioneer from Crutchfield. they recommended the polk and other speakers as a upgrade from factory. what a difference. the factory would distort but not the polks. they where on sale which is even better. install was eazy. had to remove two tabs on each speaker to make them fit. a 5 min. job with a pair of end nippers not a problem at all. I am happy with everything I have purchased from Crutchfield. they sell good product and there install sheets are eazy to understand. I will keep buying.

Nice Sound

Definitely a better sound than what I had in my 2001 F-250. When I pulled the panels, the speakers I pulled out were Eclipse, not stock, and these sounded WAY better than them. Powered through an aftermarket Pioneer head unit with no issues. Install was simple. After I had everything hooked up, it did leave me wanting more bass, but overall very pleased with the speakers. I had to cut and crimp the provided speaker wiring harness, but I assume that was because the previous owner of the truck had installed aftermarket speakers.

Great

These 5X7 speakers were extremely easy to install thanks to Crutchfield's excellent instruction sheet with photo illustrations coupled with the freed wiring harness adapter. I disconnected the factory tweeters in my Ford Fusion when I did the install and I'm so glad I did because the Polk's more than picked up the high end they were putting out. They sound is so smooth and detailed coupled with my Pioneer deck and Alpine power pack amp I know they will provide me with many years of listening enjoyment.

Polk Audio db571

Replaced all factory speakers in my 2007 Ford F250 supercab truck. Crutchfield advisors were great in assisting with all around good speaker. The install took approximatly one hour and half and that was taking my time. All speakers fit perfect with no modifications. Great improvement of all around sound compared to factory speakers. No amp just factory head unit. Great speakers and perfect fit.

Polk Audio db571

These speakers went well in my car and were a huge improvement over the factory ones. On has had its tweeter blown or otherwise developed a rattle in the speaker itself in the past couple months but for the price I paid for them, it's hard to be too upset over that

polk db571 speakers, good solid performance

I replaced factory speakers in my 02 Ford supercrew. Nice upgrade in sound and they seem to be well built. The instructions that were included made it easy to install. I had all 4 replaced in a little over an hour.

Polk Audio speakers

I wasn't happy with the factory speakers in my 2011 F150, so a friend recommended Crutchfield. I went to their website and found many after market brands to choose from. I called and spoke to a salesperson who helped me narrow down what I was looking for and offered suggestions. The Polk Audio db571 speakers easily installed and sound great, especially for the price. I am very pleased with the quick delivery and overall experience with Crutchfield! I have already recommended Crutchfield to my friends and family.

Pros:Easily installed without needing adaptors to mount.

Cons:None

great sound

put these in a 2008 Mazdaspeed3 GT front and back doors, these sound 100x better then stock. They dont really have that much bass but thats ok because Crutchfield sells them and Polk Audio makes them. Easy install fit like a champ, no mods needed.

Excellent Value

Excellent clarity to these speakers. They have great punch and performance while playing everything from Classical to Heavy Metal. High frequencies are awesome, and very crisp. The mid levels are very specific, and the speakers don't muddy a track in any of the songs I threw at them - you can hear the music as if each bandmember had his own speaker within the speaker. The low frequency tones are clear and do not hum, but rather thump, bump and kick effectively. I have a $150 price range Kenwood Receiver powering these Speakers, and play off a USB.

Polk Audio db571

big improvement over the stock speakers, especially with a new stereo. I installed the speakers first, so I had a good reference point of just the speaker replacement, and they do sound much better than stock.

Polk Audio db571

Needed to buy speakers because 1 of the factory spaekers in my '06 F-150 was dying. Was only going to buy 1 pair of Alpines but it happened that Crutchfield had a buy one get one half off sale on the Polks so I got 2 pairs of them.. Was told by the customer service guy that there would be a big difference in sound even though I'm using the factory head unit. There wasn't. There was a very slight improvement in bottom end but the highs are harsh and strident and there is a large hole in the mid range. Either these are not very good or the factory speakers aren't that bad. I'm disappointed in their sound especially considering that I have a full set of large Polks for my home theater system and couldn't be happier with those. Maybe everything would improve with a new head unit or an amp.

surprised

I just purchased a new ( to me ) truck. A 1999 F 150 super-cab. It had already installed an aftermarket receiver. It's a Alpine CDE-102, sounded really good. My Dad thought it was the best system he has herd in a auto before. I thought it was lacking just a bit, it was good I just thought it could be a little better. I thought the speakers were factory and thought aftermarkets would make it sound like I wanted. Didn't know exactly what I wanted but I knew a good place to look. (Crutchfield ) after surfing the site looking at all the what fits in my truck I still wasn't sure I was looking at punch from a e-mail ad , so I called the adviser hot line. the Adviser ask several questions my music and how I liked to listen and recommended these speakers. I received them in 2 days. I removed the door cards and found kenwood tri-axles. "Oh crap" not factory speakers!. Well I bought these might as well try them. Thanks Curtchfield adviser I could not be happier. these are clear and crisp. the highs and the mid-range is right there. can't wait to get my sub in now thanks again.

Good for what I have.

Great speakers for price and brand. Got buy one second 50% off. Boston makes clean sound without distortion. Not going to blow out windows but clean and crisp. Running off factory deck till satalite radio contract done. Going to power with aftermarket deck soon. These speakers need power to show full potential(like most aftermarket) but make a difference with crappy factory unclean power. Not as dynamic as infinity but alot less expensive.

Pros:Cleans up factory "buzz" great bargin.

Cons:Need clean power to show full potential

Polk Audio db571

A clear upgrade from the Factory speakers in my 2001 F-250 Crew Cab. Perfect fit to the stock locations, and with the included wire harness adapter from crutchfield, I had 4 speakers installed in 45 min. Not a lot louder with the factory deck, but much clearer.

Pros:Great mids and highs with no distortion

Cons:I dont have enough wattage yet to reallyget all these speakers have to offer.

Cheap, easy upgrade for crap 2011 F150 stock speakers.

Vast improvement over stock. Not what I would consider audiophile quality, but considering I am using the stock factory head unit, and no amps, subs, ect. I am satisfied with the sound - for now. Install was fairly simple, thanks to the instructions Cruthfield supplied with the speakers. If Crutchfield can stand a little constructive criticism, one of the first steps in the install instructions is to remove the cover behind the inside door handle, to access the bolt, but all the sheet shows is the cover already removed. It does not give a clue HOW to remove it! I found you need to get behind this cover on the lower left corner, while holding the handle away from the door, as if you were opening it, with some sort of hook type device, and pull sharply. I have an old window moulding clip removal tool that worked perfect for this. once I figured this out, the rest was fairly simple. I would recommend connecting the power window switch, and make sure everything is out of the way from anything that moves BEFORE you reinstall the door panel. I used cable ties to secure the adapter cables to a factory harness inside the door. Interesting observation, I think I may have figured out why the stock speakers sound so bad. On the speaker magnet of the FORD speaker, it reads, plain as day "MADE IN CHINA". Sure am glad I bought American! These must have cost Ford all of 80 cents each!

Pros:Price, if you get the buy one - get one half price deal. Seem to be made from quality materials. Installation instructions included - for your vehicle.

Cons:Not a "perfect" fit. Had to use some creative screw angles to use the factory holes, or you can redrill two of them.

Great Speakers

Installed these speakers in my 2011 F-150 SCrew and couldn't be happier. Big improvement over sub standard stock speakers and very easy to install with directions and speaker harnesses. Very impressed with overall sound and bass from these little speakers, they should hold me over for a month or so before I pull the trigger on a powered sub.

Polk Audio db571

The speakers were replacements for the ones in my 2002 Mercury Villager Van (pause for laughter). This is the second set of Polk Audio speakers that I have purchased from Crutchfield for two different vehicles (the Jeep were outstanding!!) . They were initially paired with a set of 4" Polk Audios but after pulling old rear speakers found that 2 sets of 5" by 7" in the vehicle were needed. Swap was a phone cal away and couldn't have been smoother! This was no fault of Crutchfield but with a vehicle built by Mercury and Nissan (more laughter) they changed size without notice. Interestingly, the front speakers used a front adopter from Ford and the rear from Nissan. Wire cutters please.. Also when installing two of the holes have to be drilled to make them speakers fit. Directions provided were helpful but not perfect (see above Ford Nissan comments). I added a Sound Ordinance amp sub combo. This sounds great with Kenwood system. Very happy with stereo but the Ford and Nissan combo made it somewhat difficult to install. See review for steering wheel controls for further details on that. The fact that the factory stereo, with cassette was not even listed by Crutchfield as existing-customer service again unbeatable...Sweet ride!

Pros:Great sound and weatherproof. Also on sale!

Cons:Buy some posi-taps and keep them around. Very handy when splicing. Also get some panel tools. Makes everything sooo much easier! Worth the cash because once you start buying from Crutchfield your stock systems will be on e-bay and you'll want their stuff in all your cars!!!

Great OEM Replacement

Bought these to replace some under performing stock speakers for my 2009 F-150. The sound is much better now.....crisper highs and even some thumping lows. Really should be ran through an amp, but improved the sound in my truck cab just fine. Once again, Crutchfield comes through with some great speakers at a great price......Thanks!

Pros:Better sound than stock, easy install with MasterSheet from Crutchfield

Work well in my 02 F150

4 x 571's + Kenwood KAC-8405 rock. I also have a thunderform under back seat + KAC-8104D driving it. Plenty of oomph there. Pioneer 6800 HU does all the HP LP stuff well. I just need to tune it some more. Good recommendations on Crutchfield site for tuning. I think the polk's high efficiency make them suitable for use without an amp but may not make alot of bass.To get best sound drive em hard with an amp.

Pros:good price and good specs with high efficiency

Cons:None so far

Awesome speakers

An awesome speaker for the money. Sounds great, the highs are chrisp and it has enough base. Teamed speakers with a Kenwood KDC-X596, no extra amp. When I ordered them I did not realize they are "marine use" approved. Although they are installed a truck, not a boat, humidity should not effect them over time. The speakers appear to be well made. I listen to mostly country. My 23 year old son put them through their paces with the stuff that 23 year olds listen to and he was also impressed. He thought I paid more than they sell for.

Pros:Great sound. Got a buy a pair, get a pair half price deal, so they were a good value.

Cons:Although they were the same size as the original speakers, the holes did not line up. I had to elongate the holes to use the existing screw holes. Not a big deal but added some time to the install.

Polk Audio DB571

Installed these unamplified front an rear in a 2007 F150 Super Crew with a Pioneer AVH-P3200BT head unit. Very happy with the sound, a good improvement over the factory speakers. Bass is good for door speakers.

Pros:Easy to install, only trick was trimming the left and right tabs off to fit

GREAT SOUND

great sounding speaker! with pioneer deh-4400hd head unit these sound great in my 2001 f150 ext cab! great replacement for factory. if you want thumping bass in anything you really need subwoofer. I love the crisp clear sound these produce. i put them in the front doors of my truck and pioneer ts-a6874r in rear for i wanted 3 ways with little more bass in the rear. this combo sounds great and with all Crutchfield's guides and diagrams this was an easy install and all fit perfect! polk audio gives an nice crisp sound and I listen to ac/dc to van halen, jason aldean to conway twitty , and kid rock to snoop dogg! like variety of music old and new and so far all has sounded great thru these speakers!! Great buy from Crutchfield with speakers harness it was a snap, plug and play baby!! instructions for door panel remaoval was right on! 10 - 15 minutes each door!!!!! With the adjustments in the pioneer deck you can get plenty of bass through these spekers, but again trunk thumping you need a subwoofer!

New Door Speakers

I replaced my factory door speakers with these.I wanted components but didn't have space for the passive crossovers.These actually have less bass than the factory speakers but higher highs which is optimal for me as I will be adding a subwoofer soon.All in all I am happy with them.The reason for the four stars is they didn't amaze me.Then again I'm one tough customer.

Pros:good fit,good sound

Cons:not much bass,but then they're mids and highs not subs

dave from minn. mn on 10/10/2011

The first set lasted 1 month on a stock 2010 150 stereo. The second set which was covered under warranty lasted less than a 1 year before woofer started to fail. I would not buy these speakers.

Polk Audio db571

I purchased 2 pairs of 5x7 Polk Audios for my 2010 F150 Crew cab after noticing the buy one & get the 2nd at half price promotion. I was surprised how much these speakers pump out. The sound is alot more clear and crisp. The bass is more solid than the factory speakers but decent when compared to others like Infinity. The harness and the instructional guide provided by Crutchfield made this task much easier than i expected. The guide included pictures of the step by step instructions for my specific vehicle. The harnesses worked like a charm. In all, i completed this task in under 2 hours. I rated these speakers and gave them a four because of their decent bass. Still, these speakers provide plenty of listening pleasure. Thank you Crutchfield for making my purchase a seamless and pleasurable experience.

Sounds very nice compared to stock. Very clean and more realistic, no harsh highs, not much bass but these are mids not lows. I have them hooked to a deck not an amp so they could sound even better with an amp.

installed in 97 F150

The speakers went in like a dream and sound great with moderate bass and treble. most music sounds better than the original speakers. I did notice, however, that when playing music at higher volumes, the bass will flatten a bit and the treble will give off little chirping sounds if it is set too high. I'm not sure if this is the speaker or the OEM stereo so I want to be fair about this review. I am a long time fan of Polk audio. Physical quality of the product was excellent, as always. And Crutchfield is just the best at instructions and adapters, hands down Awesome.
if you are listening to standard stuff, these are great replacements. If you intend to seriously rock out, I'd look into a preamp and splitting out the sounds.

Excellent for F-150 front and back speakers

I installed this in my 2011 F-150 front and back to replace the stock speakers as Ford continues to disappoint in that department. Great fit, excellent sound. I have not installed a sub yet so I don't know how well they will do with the lows but for just speakers, I highly recommend them. Sound is very clear and the bass is pretty decent without breaking the bank. From what I have heard on many forums and now from personal experience, if you have an F-150, these speakers are the way to go

Great Option for Factory Replacements

These speakers are a fantastic option for replacing factory speakers. They may seem a little expensive compared to others but they are well worth it. These speakers were installed on my 2003 Ford Mustang and they sound great. Highs and mids sound a lot clearer and highs sound brighter. Bass does seem a little disappointing compared to the factory speakers, but the bass is so much cleaner. Playing some classic rock with these makes it seem there is an actual bass drum somewhere in the car.
These speakers would also be an excellent choice if you are planning on installing a sub.
Please note that they are 5x7 speakers and not 6x8. Most Ford vehicles use 6x8 speakers (for what reason I can't figure out. Not too many 6x8 options in the aftermarket). These speakers will fit into the factory locations but in my case I was only able to use 2 out of the 4 factory screw locations. These speakers come with self tapping screws so you can fix that if you have the space. I did not have the space to do that so I installed the speakers with 2 screws. They seem to hold just fine and there is no rattling.

Wonderful

souther32 from Georgia on 5/18/2011

2005 Ford F-250 Super Duty

Debated for a while to get this speakers...
Great decision to purchase 2 sets of them. They provide PLENTY of Mids and
Highs, Bass is not overly impressive but is very very clear sounding.
Not going to blow anyone away, but provides the best sounds of any door speakers
I have heard
With Crutchfield providing extremely easy installation instructions and wiring
adapters, you cannot go wrong with purchasing with them.
O and did I mention that Crutchfield provided easy installation instructions
with pictures? Had 4 speakers installed in my f250 in under 1 hour...

Decent

These speakers are decent, better than the factory that's for sure, good bass
and the clarity appears good. I replaced the rear factory set out of my Ford
F150, but now I am debating if I will replace the door speakers with the same
brand. Apparently, both speakers on my passenger side (front and rear) were
blown, so I can't really tell until I replace the front door speakers, if this brand
will suffice. The install was very easy, more difficulty with the truck moldings if
anything but all else was smooth.

Polk Audio db571

Andrew from Las Vegas on 4/4/2011

Installed 2 sets of these in front and rear openings of 2005 Mustang. Running off an an amp pushing 50watts rms to each speaker, with the low pass filter set at 100, it only took six months to blow 2 of them. This is considered "field wear" and is not covered by warranty, despite the amps power being rated well within Polk's stated zone. When they did work the produced sound was rich and clear. I tuned them only to produce mid/high freq.s which they did well.

Buy One Get One Half Off!!

Came home to find the package on the doorstep, grabbed a regular and a
phillips screwdriver, a 5/16 and a 9/32 socket threw my work shirt on the bench
and had four speakers installed and rockin' in 40 minutes. The OEM connector
supplied by Crutchfield worked great. And at buy one get one half off I couldn't
pass up replacing the stock speakers in my 2002 F-150 SuperCrew. They
sound awsome! Just ordered a new head unit to finish off the system.
Crutchfield and Polk Audio are two winners!!
Thanks!!

Awesome sound...especially for the price

You are going to love these speakers. I purchased 2 sets to replace the stock
speakers in my F150. Why do I love them... First off, I received them in two
days! Instructions are so simple to understand. With the supplied wiring
harnesses I replaced the front speakers in 15 minutes and the rear speakers in
about 25 minutes. The sound...awesome, but then again, with Polk Speakers what
else would you expect!
You simply can't do any better than Crutchfield or Polk!

Very nice

I have a 2011 F150 XLT. Crutchfield advisor recommended these and after reading the
reviews here I pulled the plug. I do not have a single regret. Factory speakers seemed
muddled. I had Polk in my previous vehicle and loved their sound. These do not
disappoint even powered only from factory HU. Plenty of sound which is crisp and
clean. I know the system would sound better adding a subwoofer but even without they
still put out some nice bass. Certainly will not shake the windows but enough for my
ears. I may add a sub later but will play as is for a few weeks then decide. Very nice
cost/performance combination. Highly recommend.

Great Replacement to Stock

BrendanG from Middleboro, MA on 2/18/2011

Well, I had a little issue. One of my speakers came DOA, but I didn't notice it
until almost 20 days after I installed them. The woofer was not attached to the
tweeter, so the tweeter was getting 65Watts and was just garble.
I called Crutchfield, and within 2 days I was all set. They sent me a new one, I
sent them the broken one and didn't have to pay a thing.
These speakers make some sound! I put these into my rear door speakers(I don't
sit back there so I didn't notice the tweeter was busted right away) and they do
sound amazing! They hit from low to high very well and everything in between.
If you are looking to just replace your door speakers this is a great start!

wes from edmond ok on 2/13/2011

1998 Ford F-150

i really like these they sound a lot better when you have them tuned just right but you still
get what you pay for i still wish i could afford focal alpine or pioneer

Ceaner, clearer and undistorted sound

I purchase 4 of these speakers as a replacement in my 98 F150. prior to this
purchase I had Pioneer TS-A6872R in the front that replaced my dry rotted
factory speakers. Now 1 year later my rear speakers have suffered the same fate.
This time I wanted to replace all 4 with the same speaker. I'm glad I did. These
Polk speakers are so much more pleasing to my ear. To describe the sound in
comparison to the pioneers, the mid -treble sound so much cleaner and the bass,
although not as strong as the pioneers, sound much more controlled. While I will
admit these speakers would be better paired with a sub, I still love the overall
sound MUCH better...especially considering I'm using only my head unit's power.
Thanks to Scott for the recommendation.

Excellent Upgrade

I bought a pair of these speakers to replace the stock paper cone speakers in my
2009 Ford Focus. What an improvement. Of course, Crutchfield includes everything
you need to install the speakers along with an EXCELLENT instruction sheet.
Speaker installation went off without a hitch on my car. These speakers sound
great. They are a vast improvement over stock speakers. They sound clear and
having great bass and treble. Before, all my music used to sound like a garbled,
low-quality mess. Now it actually sounds good. Highly recommended speaker set!

Excellent speakers....

This is the second time i have purchased Polk db speakers. i must say they hold up to their
name and don't disappoint. The only thing i wish they did is to make 6x8 for fords. The
sound is clear and crisp, plus the bass is definitely not bad running off an aftermarket deck. I
would recommend and have to all who ask me if they are good speakers.

Great little speakers

I replaced my 08 Superduty speakers with these and what a difference it made.
Because of the crossover built in, there is no need for an external crossover. It does a
pretty good job seperating the highs and lows. Even though they are not enclosed, they
sound surprisingly good and strong, even in the low range. They are definitely not
subwoofers, but if you want to hear clear, loud music, these speakers are highly
recommended.

Seems to be quality speakers, easy to install, sound good. Of course, beside the stock
Ford speakers(old), anything would be good. I like classical and country, I can actually
hear what is suposed to be there. Happy with the speakers and Crutchfield

Better than Stock

Definitely an upgrade from stock in my 2010 F150. Improved clarity, very nice high end for the low price. I don't think any more expensive speakers would sound better since I'm using the stock head unit, no amp. No base to speak of but that's to be expected from a 5x7. I plan to add a small sub for some base, but even without a sub these are pleasent to listen to. Install was easy with the free bonus stuff from Crutchfield; the detailed directions and the free connectors. The speaker mount holes did not match up with the ford, but it only took 2 minutes with a drill to widen the mount holes.

Great Upgrade from stock

I purchased 4 of these speakers to upgrade the stock speakers in my 210 F150
supercab. best money I could have spent. the previous truck had an after market radio
but since this truck had an integrated radio that was not possible. the speakers made
the stock radio sound better than I could have ever expected.
I have other Polk products including exterior deck speakers so I knew that they could
tolerate the elements.
I strongly recommend this product.
One thing: make sure to secure the harness that is provided so they do not get caught in
the power windows. I had one come loose and some simple plastic ties solved the
problem.

Great Speakers

I recieved my speakers in December but did not install them till January. This gave me
time to listen to my new deck through the factory speakers for awhile. Wow what a
difference!!! Even though I have only the aplified power from the deck these speakers
made a huge difference. The clarity and bass response is great. I would reccomend
them to anyone looking to upgrade their system for a reasonable price. My customer
service rep Dolly was a big help and knew the products very well. I will be buying again
from Crutchfield!! My F-150 Crew Cab sounds great now!!

A significant improvement.

I purchased these as replacements for the stock speakers in my 2009 Ford Escape,
and they did not disappoint. The mids and highs are considerably better now. The
bass is also improved, albeit modestly, but I have a subwoofer for bass anyway.
Despite their very high efficiency rating, they are definitely hungrier for power than the
stockers. I"ve had to turn up the volume on my Pioneer head unit by about 6 levels on
average. (But volume goes up to 62 and these things still get LOUD by 40 or so. Plus I
could always add an amp.) The necessity of turning up the volume also meant I had to
turn down the gain on the sub's amp a little, to maintain the sub's desired output; no big
deal. Installation went smoothly with no complications of any kind. Ultimately, I'm quite
satisfied with the performance of these speakers. However, I'm not giving them five
stars, because they won't blow you away. But they are a noticeable and pleasing
improvement at a reasonable price.

Simply The Best!

I installed a set of the db571 in the front doors and rear pillars of my 97 Ford Ranger pickup. They're classed not to fit my truck but they fit very nicely. I also ordered speaker baffles for the front doors and a new Kenwood HU. I installed the speakers first as I wanted to hear what they would sound like with the factory HU and all I can say is WOW! I've had Polk speakers for years in my home and different vehicles and these are why I keep purchasing Polk. For a 2-way speaker the highs are very clear and the bass response from this 5 x 7 is incredible, not sub-woofer sound, but very, VERY impressive. I HIGHLY recommend these Polks. Once I hooked up the new Kenwood they came to life even more. I also have the Sound Ordnance BP-8 sub on back-order which I'll review once I get it and I also plan on adding a 4-channel amp in the future. I have reviews on the Kenwood and baffles as well. As always, Crutchfield is the best customer service business I have EVER dealt with. I emailed them several times about various gear and they always respond very quickly and professionally. Two thumbs up to both Crutchfield and Polk Audio.

Great replacement for stock speakers

I got these on the recommendation of Scott at Crutchfield to replace the stock speakers in my Mazda3. I got two pairs, one for front doors and one for back doors. I am very happy. The sound great without amps. I listen to wide variety of music, classical to bluegrass to country to old disco. They sound very good across the spectrum.

db571 in a 2000 Miata

I installed these speakers in my non-Bose 2000 Miata to replace the factory door
speakers. The speakers were easy to install, fit well, and sounded good. I
had previously installed a pair of db401speakers in the windblocker, and the
combination of these Polk Audio speakers was a great combination.

Amazing SOUND!

Kyle from South Carolina on 1/1/2010

2006 Ford F-150

I bought 2 pairs of these speakers to replace the stock speakers in my 2006 F-150 supercrew. The install was pretty easy although it required taking off the rear door panels of the truck. The sound alot more crisp and full compared to the stock speakers. The bass really kicks and sounds like there is a sub but there really isn't. I was honestly amazing about how much an improvement these 5"x7"'s made in my truck! If you are considering buying these...DEFINITELY buy them! Polk Audio is amazing!

Polk Audio db571

I purchased these speakers to replace the factory speakers in my '05 F150 FX-4. I have
previously replaced the factory head unit with a Pioneer Avic-D3, also purchased from

factory speakers in my particular configuration.
As always Crutchfield service and support was friendly and helpful.

Polk Audio db571

I found these speakers to be very smooth overall. The silk/composite tweeters are very appreciated by the ears. The respose is very natural and the speakers can take pretty much whatever you throw at them. They may be 60 watts rms per speaker, but they perform as if they were twice that. Still, I think they could be a bit louder, I'm definitely going to take a look at polk's mobile monitor series with higher wattage rating. By the way I'm running them off a kicker zx 350.4 amp and a kenwood kdc-mp435u. System sounds great! I listen to abrassive music such as metal and rock mostly so I have to be picky to get a clean sound.. If you love music loud and clear!!!!, buy silk domes! and moreover buy Polk audio!!!

Really 4.5 stars

2003 Explorer w/ stock radio, no factory subwoofer Time used 12 hours Tested w/ CD "Slippery When Wet" by Bon Jovi (fav. album ever)
Summary: The speakers provide a much cleaner and crisper response than the factory speakers at mid and high ranges. There seems to be some lower response loss. The lower frequencies are coming through cleaner, but not as prominent. This may be due to factory speakers providing a "muddier" output in the low areas. Overall, I like these speakers.
Pros: Excellent high-end and mid range response. Very clean sound throughout the frequencies.
Cons: Really close fit, not "exact". No instruction on what the black rings were used for. "Perceived" some loss of lower frequencies from stock speakers.
Story: I decided to swap the factory speakers for these as part of a stereo upgrade for my X. I found these locally and visited the store. I tested these speakers on their wall of speakers against others in the price range. My test consisted of running the head unit with a flat EQ on a local radio station. Other offerings sounded similar. I then switched the head unit to a preset "rock" EQ. These speakers came alive with response. The other models did not sound as good with this EQ setting. Of the models in the price range, these sounded the best.
They came with black trim rings taped to the speakers. Crutchfield said these are not needed for my installation. Crutchfield's installation guide and telephone assistance is excellent.

So much better

Upgrade for my 02 F150 ext cab. JVC Mobile HD Radio Receiver/CD Player w/ iPod-Ready - KD-HDW10
I mainly listen to Rock and country, on occasion R&B and Hip Hop. That means this review is geared mostly towards Rock and Country.
These speakers are so much better than the factory speakers. What I wanted out of my new speakers was better/louder sound that did not distort when cranking up the tunes. That's exactly what i got on 95% of the music i have listened to. The other 5% there was some distortion at the upper limit but turning it down just a little fixed that.
Ive bought and installed a few speaker upgrades for my vehicles throughout the years and in every case I found myself wanting (not needing) more bass. I don't necessarily want to rattle the windows I just want it to HIT HARD at the right time. That would be my only (whats the right word) grip about the speakers. On some songs you don't get that Kick I like. Im no expert, probably this is the case with all setups similar to mine, after market HU and aftermarket speakers. Maybe more expensive speakers will give you that kick 100% of the time(does that even exist on a budget?) , i dont know. But those "better Speakers" cost waaaay more than what i paid. Maybe adding a amp would help in that aspect.
Over all i am very satisfied with my purchase Ordered on Wednesday, they shipped ground that day, arrived Friday. Installed 4 speakers in just under 2 hours. They even included instruction that were very helpful!

Incredible Sound!!!!!

I installed theses speakers in my 2004 Ford Explorer w/Audiophile System and let me tell you the difference these speakers made. I was a little skeptical at first being that I was happy with the way the stock system sounded, well little did I know what was missing. After installing these speakers, which only took about 1/2 hour, I turned the radio on and wow!!!!! These little speakers have some very decent thump for their size and amazing highs. I replaced all 4 door speakers and I can't believe the sound quality. So if you are looking to upgrade your sound system and don't want to spend a fortune doing it, these Polk Audio DB571's are the way to go. With the supplied connectors supplied by Crutchfield, installation was literally a snap. Once again I have to commend Crutchfield on their installation accessories and expertise on recommending these speakers for my Explorer.

Product review and service

A friend of mine gave me a JVC head unit to replace existing factory unit in my Expedition. I order the required harness and Polk db571 to replace 4 factory speakers as well. The resulting sound is just great. Kudos should also goes to Crutchfield support staff who guided me in my installation issues. I'd like to add a sub-woofer at some point and surely would order it again from Crutchfield.
Well done guys !

polk db571 (s) into '96 ford ranger

speakers replaced originals which were not too bad...system was Ford's better stereo with included amp...fitment was good but not perfect...installation into front doors was pretty easy compared to years past...Ford did speaker changers a favor there....
not an expert by any means but think these speakers are substantial improvement...pretty much big sound and an adequate presence....
Crutchfield's installation aids, as always, were specific and easily followed...helpful/useful and speakers were offered at an extremely attractive price....

Speakers fit both doors and rear deck area. However, they take a tad of finesse when installing the deck units. The screw holes are just a shade off. Keep all screws loose until all the screws are installed and there will be no problem. Install instructions are on the money and the harness makes it a snap. Good audio, even from the original radio.

Really impressed!

Chris from Avondale, AZ on 1/24/2009

I am Really impressed! OK so I said it twice. But these have been a GREAT addition (as replacements) in my 2006 Explorer Eddie Bauer. Huge improvement in sound, clarity, low and high end. Work well with the factory sub (which may be next for upgrading) and certainly blow away the factory junk that was in the doors. Installation is a breeze with the multi-point install ears on the speaker frame.
These are my first and certainly NOT my last set of Polks for future vehicles/home.

Just Ok

I had these installed in my 2009 ford focus sedan. There was a slight improvement over the stock speakers. I felt a little more bass, mid range improvent but was not all that impressed. They are just ok. Crutchfield was quick to ship and included a plug in play harness that made the actual installation a breeze. The speakers fit the stock location without a need to drill new holes. Note to the 08/09 ford focus owners, the new ford focus is not very user friendly when it comes to installing speakers. Front doors have a different set up from the back ones. I have encountered some damage. I will the speakers 2 out of 5 and crutchfield 4.5 out of 5 for their service.

Great Speakers for the Money

These speakers really surprised me when I heard them. I did not think I would notice that big of a difference from the factory speakers, but I was definitely wrong. The sound quality is great! Sounds are more distinguishable and I now hear sounds in songs that I never even heard before. The built in tweeter sounds great! The speakers sound great for the price and are definitely worth the upgrade. The bass as expected in door speakers is not great, but it is a much cleaner and better sounding bass than the factory speakers. I recommend these speakers to anyone who is looking for great sounding speakers and on a budget.

Great Deal

Cole from Destin, FL on 12/18/2008

These speakers are a great upgrade from the factory speakers! I was somewhat intimidated to install these myself... Removing front door panels
and the rear speakers are inaccessable unless you remove the back SEAT! BUT with crutchfield's instructions it was easier than I expected. Had both
door panels off and the back seat removed in about 15 minutes. After that it was simple. Perfect fit.
The sound improvement was clear from the first note! Dramatically improved highs and lows! Plus more volume from these speakers than I expected. No more muddy sounding factory speakers for me! I would recommend these to a friend.

The install was easy - the instruction booklet was great, pointing out what to pull and in which direction so that I wouldn't break anything, as well as pointing out all the hidden screws and how to remove/replace them. I had the new speakers (and baffles) installed in about 20 minutes.

2003 Ford F-150

I purchased these speakers while on sale with a Pioneer DEH-P7000BT CD
Receiver. I recieved the speakers first and installed them in my 2003 F-150
with the stock head unit. What an amazing upgrade. I was able to hear
sounds in songs I wasn't able to before. I broke them in for a while when I
was waiting for my aftermarket headunit. I recieved and installed the deck
about 3 weeks later (It was on backorder) When I finally got the deck in I
cranked up the volume. The low-end distortion is very noticeable at high
volumes. I'm ordering a Blaupunkt 210a to handle the low end, I'm hoping
it will fill out the rest of the sound. I'd definately recommend these
speakers to someone wanting more mid/high definition. If you want clarity
at low end, a sub is almost a must. 4/5

Great Speakers for the price!

i hooked these up in a 2004 mustang in the doors and in the rear deck. They replaced the speakers in the Mach system with a aftermarket Pioneer Premier head unit. im running all 4 on head unit power and i have them limited so they wont try to play to low of bass. they fill in the highs and the mids very well without being too shinny or bright sounding. i bet they would osund alot better with a 4 way amp which i will try in the near future.
easy install in the factory Ford openings (6x8's) with no depth issues
i would deffiantely recomend these to a friend

Nice Upgrade

I installed these speakers to replace my front and rear factory speakers, and they sound like 100X better! The mid to high range is definitely the highlight of these speakers. I listen to a lot of metal and hard rock and these speakers give the guitar riffs justice. The bass response is great, but not excellent. I have two 12" subs which provide me all the bass i need. These speakers do a great job of staying just as loud as the subs so my music doesn't get drowned out. I recomend these to anyone trying to upgrade their existing factor speakers, there's no comparison between aftermarket and stock speakers. Such an awesome improvment! Installation was a pain, but that's how it is with every kind of car audio equipment.

Great Improvement

I took out the factory speakers in my 2003 Ford Explorer and replaced them with these in front and back doors. It is a significant improvement over what was in the vehicle. Much more bass and great highs. My wife noticed it was much better since the system in our other vehicle is much better than this one. I would recommend these as an upgrade must. Also, the information and wiring that Crutchfield sent with the speakers made the install a breeze.

Polk Audio db571

Jeffrey from Michigan on 9/20/2008

I replaced all four speakers in my 2003 F-150 SCrew with these Polk speakers and they are fantastic. The only thing that they could improve on is the bass response. I have a Sony head unit and had to use the low pass filter to cut the deep bass out so the speakers wouldn't distort. I also had to turn the treble down because the tweeters work real good!
For the price that Crutchfield sold these, you cannot go wrong.

Great upgrade!

These make a great upgrade from the stock speakers. Easy install with the master sheets, and the included wiring harness.
I realize that an amp will fully bring out all that these speakers have to offer, but still, these are a vast improvement!
Try the Polks out, you won't be disappointed!

Good midrange, but too much high end

I'm always looking for as natural, listenable, and "hi-fi" a sound as possible, judged over the range of source material available; not a "boom-sizzle" sound. This speaker's claim of a more complete 2-way crossover (compared to the more typical one-sided crossover) held out the possibility of finding that. The speaker does include an inductor in series with the woofer, which shelves down the high end of that driver, in combination with the woofer's own rolloff. The net crossover to the tweeter works well and the resultant midrange is smooth and natural. The tweeter, though, screams at 8 kHz. If you like sizzle, that's good, but I'm running the parametric EQ in my head unit with an 8 kHz notch set to maximum to compensate. I'm also taking a bit of 100 Hz out to reduce a hint of boominess, which becomes more than a hint when all four door speakers are faded in. With good source material and this EQ, the speakers can sound very good, but most FM and many CD's already spit too much, and I have no EQ room left to turn the highs down any farther. Overall, I guess I'll keep them, but I wish someone would make a really hi-fi car speaker, not a sound effects speaker.

Great Speakers

I installed these speakers on all four doors of my '06 F150 SCrew. Easiest install I've ever done took me about 30 minutes all 4 doors using the crutchfield mastersheets. Sound alot better than stock. A great upgrade. Buy these speakers you won't be disappointed. Good sound quality.

Obvious Improvement

I replaced the stock 6x8's in my 08 Mazda 3 with these 5x7's. The improvement is clearly noticeable. I have a "reference song" that I always use and was so disappointed when I played it on the stock system after getting the car home. I knew then I would have to make some purchases. I'm sticking with the stock head unit, but the speakers had to go. Big difference. Even my girlfriend could tell the difference, and she really couldn't care less about this type of thing. She was very surprised how much better the song sounded after installing the set of 571's. I only have the fronts in right now and expect a little more improvement once the back go in. I do have a sub in the trunk, but when I fade to the front, they seem to have the bass I'd expect. They sound better than the 6.5 Kenwoods I had in my Colorado.
On top of the good price, Crutchfield's great service, communication and support made it a no brainer. After years and years of purchases, Crutchfield continues to impress. Someone may save a buck elsewhere, but the trade off isn't worth it!

Amazing sound for the money

i just installed 4 of the 571's in my F 250 Supercrew. The sound is dramtically improved over stock, and well worth the $ I paid. Frankly, the only problem is that I can now HEAR all of the other weaknesses in my system, and am getting ready to order a sub and 2 amps!!!

Great Sound, excellent price!

The installation of 4 speakers in my 04 F-150 took a little more than an hour. They fit nice and snug in the factory location. I didn't change my stereo unit, and the sound is much more clear and crisp. I'm able to take the volume much higher without distortion.
The only issue I had was my front factory speaker had a small tweeter installed that was powered by the front primary speaker. I wasn't sure how to connect the tweeter to the Polks. I'll probably call the tech support line to ask whether I should splice the tweeter into the main power feed. Even without the tweeter (factory), the sound is great.

Nice for the money

I just purchased these. I replaced
the factory speakers and used the factory head unit and sub. These are
very nice speakers for the money. They're not the greatest I've ever heard
but they do a nice job and are better than the factory set. Crutchfield was
great, got them in only 1 day also the included wiring harnesses were
perfect. The instructions for installation in my 06 Moutaineer were spot on
and really simple. These are well worth it for the money.

Outstanding Sound and Value!!!

I replaced all 4 factory speakers in my 01' F-150 Supercrew with these and I couldn't be more happier with the outcome. I wanted to see how loud I could go with them before they started distorting but I never got that far because my ears started hurting. They sound extremely clear and crisp and I couldn't be more pleased with this selection. Thanks Crutchfield!

AWESOME!! Pleasantly surprised

Robert from Garner, NC on 5/26/2008

I got a pair of these speakers with the buy one get one half off special. I placed these speakers behind the seat in a 1996 Dodge Dakota knockaround truck. Long story short--I got carried away with the system in the truck--and these speakers, with their incorporated crossovers, the mids and highs are crisp, clear and rich in sound.
I'm used to higher end speakers in my vehicles, but honestly, these speakers rival any I have had before. of course I am certain it helsp being in such a small cab.
Based on the price of these speakers, you truly cannot go wrong with them. if you're going to have an amp, and a separate sub--these are the way to go.

Good Sounding Speakers

Justin from North Shore, MA on 5/24/2008

Just popped a pair of these in the front doors of my 03' Ford Focus, replacing a pair of factory speakers that left a bit to be desired.
The first thing I noticed about these is how CLEAR and BRIGHT they are: after fading the audio all the way to the back (where factory speakers are still installed) the sound from the back sounded muddy and undefined in comparison to the new Polk's in the front.
On the default setting, I felt that these speakers felt almost OVERLY bright, and the bass response, for me, left something to be desired. After a little tweaking on my Alpine, I was able to achieve a pretty decent balance between the highs, mids and lows.
I agree with a previous reviewer: these speakers sound MUCH better at higher volume levels: I found at low volumes, bass and low mids were difficult to hear over high hats, snare drum, and vocals.
Overall, I'm happy with these speakers. I think once I have a matching pair installed in the back, the balance of sound in my vehicle will greatly improve.
As always, great customer service and free install instructions and parts from Crutchfield, they were top-notch as always.

Great Speakers!

Awesome sound! I replaced my 2005 F-150 FX4 SuperCab stock speakers with these and the clarity couldn't be better! Even with the windows down, the speakers sound like they are right at ear level. I would recommend these to anyone looking for a good set at a reasonable price. One thing though, only 2 screws would fit on my rear SuperCab doors, but is still held in very tightly. Had to bend the brackets on the edges of the speakers for them to fit into the front doors, but that was no biggie either.

Polk Audio db571

jussa79 from SLC, UT on 4/18/2008

I put a pair of these in the back corners of my '95 F150 ext. cab, and what a difference! I only use this truck for recreation and grunt work, so I couldn't justify spending lots of money on extras for a vehicle I don't drive everyday. I was pleasantly surprised at the level of sound quality you get for the price. I'm just running these off the in-dash receiver, no-amp, but I'm getting great response and it is the perfect match for the confines of a truck. It will be nice to have quality tunes this summer when I'm out camping and again in the fall when elk season starts!
Let me add that Crutchfield is the greatest, hands down! Local big box stores don't have near the quality or selection Crutchfield does. I only set foot in them to buy movies, there is absolutely no reason for me to even look in the direction of anything else there. Qualified help is just a phone call away, and everyone I have ever talked to at Crutchfield is friendly and professional. They send you everything you could possibly need for installation in your vehicle, at no extra cost!!! If you've never bought from Crutchfield before, I'm telling you that you will never look back!

good bang for the buck

I paired these up
with a set of
DB570's for my 04
Interceptor. The
doors fit well, the
rear deck leaves the
slightest air gaps
when centered into
the opening... I'll
have to silicone the
backside of the
install or something
to seal them tight.
The sound is much
improved over stock.
When I listen to
speakers in a store
location, my ears
can really ring on
the tweeters. These
are were so smooth,
I thought they would
be a great fit in
the car. Well,
cymbals and other
high notes are a
little lacking in
what I was expecting
(nothing a little
tweaking on the Sony
CD player can't
overcome thou)...
These speakers come
alive with higher
volume levels, but
then the adjustments
I made to bass and
treble sound
terrible... don't
know what I'm going
to do about it...
Kinda blows the
"don't mess with me"
look, when other
cars can hear the
speakers blaring
inside mine.
This is the largest
car I've ever owned
(probably just short
of the biggest made
anymore), and the
stereo imaging is
leaving a bit to be
desired. I really
don't believe it's
the speakers issue,
most likely the
factory speaker
locations.
Overall, I'm happy
with the puchase.
For the price, I'm
not sure if anything
would have been a
better choice for
this vehicle.

2005 F-150 Stx install

I just installed these in my 05 f-150 and let me say these are the best speakers i have ever owned you can turn your music up as loud as you want to without it becoming muffled i would deffinaly reccomend these speakers to anybody. These speakers are great if you just want a little bass without a subwoffer i put dyna matt behind mine and my truck sounds like it has a sub in it with these speakers.

The speakers fit the stock locations with no modifications. I added some sound deadner behind them on the outer door skins. Base response is much better than the stock speakers ever could reproduce. I am still running the stock Ford radio at this time and these speakers have much better range then the originals. The vehicle is a 99 F150 quad cab with the rear 1/2 doors.

2004 F150 Factory HU

I put four of these in my 04 F150 Extended Cab. I have the factory Ford Premium Sound 6 disc system w/XM SAT. Instant improvement. Greater clarity and the much louder. Bass is better too. The more I play them the better they sound. I highly recommend these for the F150. Once again Crutchfield gave my exactly what I needed.

94 Ranger Install

Quick easy install. Instructions stated 5mm fasteners mine were actually 7/32" not a big deal. Wire harnesses are great! Rears took 30 minutes, fronts 60 minutes. Made an outstanding improvement over those factory "premium speakers". Good response and clarity except for the really low freqs. Add a powered subwoofer for the bottom end and it's a sweet sounding cab. An excellent value.

Great Bang for the Buck

My son gave me an Alpine CDA-9883 Receiver for Christmas for my Ford f150 pickup. I was very pleased with my new stereo but not very happy with the original factory speakers. I compared several different speakers on Crutchfields site in the up to $200 range. The Polk db571 speakers had the best customer reviews from owners with pickups. I also know that Polk Audio has a reputation for great sounding speakers. Installation of of the Polk db571's was pretty easy with Crutchfield's installition guide. After allowing a couple of weeks 'break in' I can say that I am very pleased with the sound from these speakers. They are very clear and bright sounding speakers with very accurate midrange. Their only weakness is at the very low end, but then they are only a 5x7 so I wouldn't really expect more. I will be adding a powered subwoffer to round out my sound. At $99.99 and get the second pair for half price it's hard to beat the sound and value of the Polk db571 speaker.

Installed these in all 4 doors of an F-150 supercrew and powered them with the Alpine 40Wx4 amp. They sound great but I did need to add the Polk 1&quot; dome tweeters in the front doors for more clarity. It is worth the extra money.

Great Sound and Price!!

I have these installed in the rear doors of my 03 F-150 and the sound is great!! I have always liked pioneer speakers until I heard these. Let me tell you, these make an ordinary song sound great and you hear sounds you didn't know the song had!! A very good speaker you can't go wrong with.

Installed 2 sets in my 2002 F150 FX4 ext. cab (front/rear). Big improvement over factory speakers although the stock stereo doesn't allow these speakers to perform to potential. Still, a great upgrade!<BR>Did have to drill two additional holes for each speaker which was very simple.<BR>Total install time: 90 minutes. Great instructions from Crutchfield as always.

They will sound better but remember a factory head unit naturally reduces base when you turn up the volume. So yes they will ... but if you are looking for even better sound, you can get aa sound processor and your factory head unit will act like an aftermarket. All that said ...... they will still sound better just by upgrading you speakers.[ Michael Dec 05, 2015 ]

Used these Polk speakers with both the factory radio and a mid price Sony unit. The speakers sound a bit better than the factory but the factory radio is horrible. If you get even a basic aftermarket radio you will be very happy with the Polk speakers. They are excellent for the price with surprisingly strong base. Very good choice.[ Tomi Dec 05, 2015 ]

I forwarded your question to an Advisor and they responded with the following: These Polk speakers can handle all the watts the Power Pack outputs which means you can set the gain to whatever sounds the best to you.If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.[ Krissy Sep 04, 2014 ] Staff
